Special Report:Production of flowers in greenhouses in Holland
By Irrigazette (1/2023)
On a rainy June morning, accompanied by Arjan Van den Berg, head of sales at NaandanJain for northern Europe, we travelled to meet the flower producers in the Westland region, in the south-west of Holland.
We passed through a residential district, with greenhouses and dwellings with well-kept gardens scattered and we then arrived at the premises of U Grand, who are producers of chrysanthemums using state-of-the-art technology.
When we entered the greenhouse, I was overwhelmed by the humid and stifling atmosphere, and thoroughly impressed by the vast array of colourful flowers that extended as far as the eye can see. Rose-coloured, yellow and white chrysanthemums follow one after the other in this vast greenhouse that covers some 10 hectares.
“The 4 pillars of the flower’s development: Heat, light, irrigation and CO2”.
“We can expect an optimum level of growth when these four components are optimised”, explained Arjan.
The flowers are irrigated with rainwater. The gutters installed on the roof of the greenhouse enable the recovery of this water. It is directed towards an outside reservoir where the water is stored and then injected into the irrigation system.
The flowers are irrigated with NaandanJain’s Green Spin micro-sprinkler system, consisting of two rows of micro-sprinklers spaced 1.25 metres apart. The irrigation system is positioned at three metres above the flowers.
The system operates in a closed loop: the water that is used to irrigate the flowers is recovered, treated and reinjected back into the irrigation system. The whole unit is irrigated almost exclusively with rainwater, except when it is extremely dry.
NaanDanJain solutions for Green house flowers production are versatile, with a wide range of irrigation solutions being applied according to specification of growth stages and plant’s needs.
